error communicating with the remote browser. it may have died.

This usually happens when you are trying to close the same webdriver instance multiple times. Do you know what happens in

super.teardown()

? When I checked the selenium4j source, it extends junit Testcase. Your

super.tearDown

will be calling jUnitTeardown and would be killing the browser instance before

closeSeleniumSession()

is called.

You can put that

closeSeleniumSession()

before

super.tearDown()

.

 

 if(driver != null) {
                driver.close();
                driver.quit();
            }
